# inetd.conf    This file describes the services that will be available
#               through the INETD TCP/IP super server.  To re-configure
#               the running INETD process, edit this file, then send the
#               INETD process a SIGHUP signal: 'killall -HUP inetd'
#
# Version:      /etc/inetd.conf 6.0     Mar 12 2000
#
# Format:
# &lt;service_name&gt; &lt;sock_type&gt; &lt;proto&gt; &lt;flags&gt; <user> &lt;server_path&gt; &lt;args&gt;
#
# For security reasons, all services are turned off by default. Uncomment (or
# add lines) to have services started by inetd (see inetd.conf( for details).
#
# Don't forget to also edit /etc/hosts.allow for services which are started
# through tcp_wrappers (/usr/sbin/tcpd in the configuration lines below).
#
# Note: Some servers (typical examples: Web servers like Apache and MTAs like
#       Sendmail) run usually in stand alone mode, i.e. they are _not_ started
#       by the inetd. They are started at boot time (or manually) and keep
#       running.

ProFTP (standard TurboLinux ftp server)

# Warning: the authentication information for ftp goes as clear text over
# the net. This is especially dangerous if the same login/password combination
# can be used for any shell logins (telnet, ssh). Make sure remote ftp users
# have either /usr/bin/ftponly or /usr/bin/passwd as their login "shells".
# If you choose passwd, they can change their ftp password using telnet
# without having a real shell account on your system.
